Just the other day a mom shared with me a tip for any of you who like to use (or may be considering) Horizons Math. It is a product that is available through Alpha Omega Publications. She was delighted to find that the Horizons Math package available through Sonlight Curriculum includes not only all the books, but also all the manipulatives needed. She liked not having to look up and order all those items separately.
I also noticed on Sonlight that they offer a Horizons Math Readiness Evaluation. This tool will help you correctly place your child in the Horizons Math level best suited to his or her ability.
Here are some of the great things other parents are saying about Horizons Math.
